JOEL MOSIMAN, OF FALLS CITY, NEBRASKA.

TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 333,658, dated January5, 1886.

Application filed November 2, 1885.

To all whom it may concern:

Be it known that I, JOEL MosIMAN, of Falls City, in the county ofRichardson and State-of Nebraska, have invented certain new and usefulImprovementsin Traction-Engines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, and to theletters of referencemarked thereon, which form part of this specification.

My, invention relates to traction-engines; and its objects are, first,to augment the effective action of applied power; second, to decreasethe strain on the rear drivers; third, to secure a uniform wear of theparts; fourth, to provide for the passage of obstructions withoutdetriment to thedrivers or the mechanism; fifth, to so distribute theimparted energy upon the wheels as shall cause them to operatesynchronously and actuate equally the burden; sixth, to provide for thevariable exigencies to which the engine may be called by simple media;and, seventh, to attain these ends with structural simplicity andeconomy of operation. I accomplish these aims by the mechanismillustrated in the accompanying drawings, in which--- Figure l is a sideelevation of a tractionengine embodying myimprovements, showing theirrelative location and the manner of theircoactionineffectingthedesiredpurposes. Fig. 2 is a plan view of theactuating mechanism; and Fig. 3 is a detail view, partly in section, ofthe bearing J, which serves to hold the axle of the front drivers.

The same designationsindicate corresponding parts in the several views.

The power-piston incident to engines of this character actuates theshaft on which the Wheels N O are concentrically mounted. The former isa geared pinion, which revolves the gear-wheel M, while the latterserves as a flywheel. The wheel M imparts its rotation to the pinion B,on whose shaft 0 the bevelwheel A is also mounted. The pinion B mesheswith the pinion P on shaft P of the rear driver, thus operating thesame. The bevel-wheel A in turn actuates the shaft E by means of thepinion D. This shaft is held in bearings F, and its terminal pinion Gtransmits the received motion to the crown-wheel Serial No. 181,660. (Nomodel.)

H, which may be of different forms to secure variable effects,and iscentrally secured to the shaft I, that depends by a universal joint, J,from the engine. A curved rod, L, secured by nut L, steadies the base ofthis shaft, and at its lower terminus a bearing. J, is secured, topermit the revolutions of the shaft K by reason of the wheel K (on saidshaft) and the wheel H being meshed. Chains S S, having suitable hooks,R, to which draft may be applied, are provided with terminal universallinks H Rsecured near the respective ends of the front axle, that serveto effect the diversion of the same, and so guide the machine. It willbe understood that the aim of this construction is to cause the frontwheels to assist in driving the engine,and thus the power and strain areso equally distributed that the wheels operate at the same time and wearevenly, as well as preventing the jarring motion incident to enginesmoved solely by rear drivers. It is apparent,also,that other mechanicalmedia might be substituted for those illustrated without materiallyaffecting the results secured. Such modifications I deem within thescope of my invention.

Its operation is as follows: The motive power effects the rotation ofwheel 0, on whose shaft is the pinion N, which transmits the energy topinion B by means of gear-wheel M meshing with both. The motion of thepinion B as well causes the revolution of the rear drivers (by meansofthe geared pinion P) as effects the actuation of the front drivers,(because the bevel-wheel A imparts the motion of the shaft G to theshaft E by the pinion D, and it is thence taken up by the crownwheel H,which is in gear with the pinion G.) The crownwheel H in turn rotatesthe geanwheel K, which is rigidly secured on the shaft K. Thus thesteam-generator is applied mediately as well to the forward wheels asthe rear ones, and the locomotion is correspondingly facilitated.

Having thus fully described my improvements, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. The concentric gear-wheels N O on the same shaft,operated asdescribed, in combination with the gear-wheels M B 1? A, the shaft E,having terminal pinions D G, the toothed wheels H K, and the shaft K,whereby the In testimony that I claim the foregoing as front and reardrivers are simultaneously immy own I affix my signature in presence ofpelled. two witnesses.

2. The concentric gear-whee1sN O, mounted 5 on the same shaft, operatedas described, in JOEL MOSIMAN.
